AMD Ryzen 9000: Zen 5 processors for powerful desktop computers
CPUs with Zen 5 architecture are said to calculate 16 percent faster than Zen 4. Four Ryzen 9000 processors with 6 to 16 cores will be available from July.

AMD boss Lisa Su has presented the first Zen 5 processors for the AM5 version in the run-up to the Computex IT trade fair. The Ryzen 9000 "Granit Ridge" should be particularly suitable for 3D games and creative applications. Compared to its predecessor Ryzen 9 7950X, the new top model Ryzen 9 9950X retains 16 cores with a maximum clock speed of 5.7 GHz, 64 MByte level 3 cache and 170 watts of thermal design power.
The new Zen 5 architecture, of which AMD reveals a few aspects, is intended to provide an average speed increase of 16 percent: The revised jump prediction is intended to achieve a better hit rate and shorter latencies. The developers have also widened the CPU pipeline and vector units for higher throughput. AMD promises twice the throughput for instructions in the front-end and for transfers from level 2 to level 1 cache. The performance of AI and AVX512 instructions is also doubled. However, unlike the Ryzen AI 300 for notebooks, AMD does not mention a hardware AI unit (Neural Processing Unit, NPU).

AMD only compares the performance of the Ryzen 9 9950X with the Intel Core i9-14900K (8P+16E cores). In applications such as the Blender rendering program, which benefit from many threads, the new 16-core computes up to 56 percent faster than the Intel CPU. Based on our measurement results from the comparison test of the Core i9-14900K and Ryzen 9 7950X, the Zen 5 processor should be around 30 percent faster than its Zen 4 counterpart in multithreading. In office applications with few threads, the lead over the Core i9-14900K shrinks to seven to ten percent, according to AMD. In 3D games, the Ryzen 9 9950X achieves a 4 to 23 percent higher frame rate than the Intel processor.
| Ryzen-9000-Prozessoren für AM5 | ||||
| CPU | Kerne/Threads | Turbotakt | L3-Cache | TDP |
| Ryzen 9 9950X | 16/32 | 5,7 GHz | 64 MByte | 170 W |
| Ryzen 9 9900X | 12/24 | 5,6 GHz | 64 MByte | 120 W |
| Ryzen 7 9700X | 8/16 | 5,5 GHz | 32 MByte | 65 W |
| Ryzen 5 9600X | 6/12 | 5,4 GHz | 32 MByte | 65 W |
Six and eight cores with 65 watts
In addition to the 16-core, AMD has introduced three other Ryzen 9000X processors: As before, the Ryzen 9 9900X, Ryzen 7 9800X and Ryzen 5 9600X are each available with a twelve-, eight- and six-core respectively. In contrast to the predecessors of the Ryzen 7000X series, the chip manufacturer has lowered the thermal design power for these. The twelve-core processor operates with 120 watts instead of 170 watts (Ryzen 7 7900X). The Ryzen 7 9800X and Ryzen 5 9600X now have a TDP of 65 instead of 105 watts compared to the Ryzen 7 7700X and Ryzen 5 7600X.
AMD has also introduced some changes to the underlying platform. Although the AM5 version with PCI Express 5.0 and DDR5 RAM will remain the same for years to come, the new high-end chipsets X870E and X870 are coming with the Ryzen 9000. USB4 and PCIe 5.0 on the PEG slot and M.2 slot of the CPU are now mandatory for motherboards with these. AMD also promises higher speeds for overclocking memory modules with EXPO profile.
